Late last summer it became apparent that the killjoys at Norfolk Southern were embarking on a project to resignal the entire Altoona terminal area which for the 100+ years have been under the auspices of ALTO tower, which I had
visited previously in 2005. This was coming on the heels of a similarly mean spirited project to replace the PRR position lights up and around the horseshoe curve and unlike a number of other recent resignaling projects I was not going to be caught flat footed and therefore resolved to drive out the 3+ hours to Altoona to document what was there before it all came crashing down.
Unfortunately my schedule in the fall of 2011 was quite full and combined with the fact that many people didn't know when the project would be completed and that there was a Fall Foliage running out of Altoona and around the Horseshoe Curve on October 1 I made the choice to pick that weekend for my trip. I say unfortunately because the weather was just a few hairs short of completely unworkable with a light to moderate drizzle falling over the entire day with ambient lighting about what you would expect. Doublely disappointing was that my first trip was in only slightly better conditions so it looked as if every time I was to go to Altoona the clouds would roll in and the sky would open up.
Anyway armed with a pair of cameras, one a high resolution DSLR, I set out in the wee hours of Oct 1 in order to make it to the "Brickyard" automatic signal west of town to snag a picture of the Bennett Levin PRR E8's passing under it. After that I would head downtown to take as many photos of ALTO tower and its related signaling as I could and then I could head out to see if CP-ANTIS was part of the re-signaling project as it's interlocking hardware dated from 1981 instead of the 1970's or before for the rest of the Altoon Terminal. All said and done I took about 500 photos that day which are all visible
in the full gallery.
We begin at the Milepost 238 automatic known as "Brickyard" which is also the distant to SLOPE interlocking, which itself is under direct wire control from ALTO tower. This section of the main line has three tracks, the outer two running under Rule 251 with only the center track #2 being bi-directional rule 261. Both eastbound signals on tracks 2 and 3 can display / over / for Slow Speed moves at SLOPE as SLOPE has a very short signal distance to ALTO and will display Slow Approach instead of Approach when a Stop signal is displayed at ALTO. The Approach Medium indication available on track #1 is for 1 to 2 diverging moves at SLOPE.
The MP 328 signal gantry
was in a bad way
with the uprights separating from the concrete footings and 1930's era
signaling with tar impregnated cotton insulation around the signal cable
wires. Still the replacing it with cheap Darth Vader masts on an
ungainly 4 track wide cantilever is just insulting the the home of the
PRR, especially for a railroad that recently installed brand new N&W
PL's in its home of Roanoke, VA. Anyway all of the signals up and down
the eastern slope are approach lit and were able to provide warning of
the approaching Foliage Charter.
PRR E8 #5711 was heading the charge up the grade. The charter's route was to head up and around the curve before heading back through Altoona, up the N&BE to Lock Haven and then down the Buffalo Line to Harrisburg before returning to Altoona (I think).
On the rear was Bennett Levin's PRR 120 and a couple other PV's
providing the first class consolidations behind 4 Amfleets and one
Metroliner Cab Car.
Unfortunately I left the Brickyard just a few minutes too soon as the
Eastbound Pennsylvanian rolled by as I was waiting to cross the main
line at the grade crossing just south of the signal location. Amtrak
P42 #51 was providing the power that day.
After parking at the Altoona Railroaders Museum I walked over to the
17th St bridge which provides an uninterrupted view of ALTO interlocking
and tower. The tower which dates from the first decade of the 20th
century was deceptively given a new coat of paint just a few years ago
by NS. Here we can see the eastbound signal gantry directly adjacent to
ALTO tower and governing movements on tracks 1 and 101, which is just a
short siding between here and SLOPE, as well as the new 3 track
cantilever replacement. The new ALTO interlocking will
encompass the space between here and the western limits of SLOPE
and get rid of the old pusher pocket and replace the right handed yard
ladder with a new universal crossover arrangement with the helper tracks
pushed off onto the south side of the line.
It wasn't too long before the E8's showed up again. #5711 was still in
the lead as there is a loop track west of the Horseshoe Curve at CP-UN.
The charter was run in conjunction with the annual Altoona Railfest
which wasn't very festive due to the rain.
Here is a video of the move passing through ALTO interlocking.
Here we have PRR 120 passing under the famous ALTO westbound signal gantry which dates from the Penn Central era when the State was installing the 17th St bridge and needed to move things around a bit.
Heading in on track #2 right behind the Charter was an NS helper twin
pack composed of SD40-2's 6312 and 6301. Here they are making a
diverging move from track #2 into the helper pocket although their final
destination would be the Altoona Yard.
Video of the helper set making the diverging move.
Of the 5 tracks the ALTO beam gantry spans, the center one is a pocket track designed for helper sets like 6312/6301, seen here diverging onto track 1, to lay over and be attached to the rear of through trains before they begin their assault on the eastern slope.
A rather wet ALTO as seen from the rear quarter. The whole area is
highly accessible from local roads, although be prepared to hug the curb
as the "
PRR Expressway" lacks both sideways and a shoulder on that side.
